Race Tech Emulators and YSS PD valves

[kenny5000]

After getting the idea in my head that I need to get the fork performance of my Husky (in the build up stage but should be complete within the month) matching the rear Works Performances shocks that it has, Im now thinking about some emulators. I am just wondering what peoples opinions are, pro/cons etc and ease of fitting and adjustment. Also any info on the YSS version.

Cheers

Sorry to hijack the thread but does anyone know the difference between Yss and the racetech emulators?
Are they the same?

im still trying to find out wtf a emulators is

Emulators provide a sort of shim stack valving to damper-rod forks. Short version is that they significantly improve the performance of old style (pre-cartridge) forks by eliminating the spike on fast hits.
They don't make the old forks as good as a set of properly set-up cartridge forks, but they go a long way toward it.

Personally, I've been very happy with the service I've had from RaceTech. They've given me no reason to avoid giving them my money.

[Paul552]

Nathan have you fitted them yourself?
Is there much to it?

I had racetech fitted to my yz125d and it cost me like 900 bucks and they where harsh as.
I emailed racetech and they told me to change the emulator spring and they were heaps better.
I would like to fit some to the cr125re I am building but not sure what machining is needed.
I will stear clear of the Yss so thanks for the tip.

$900 bucks shit he seen you coming , They sit on top of the damper rods , then you have to drill bigger holes in the damper rods or more holes , shorten the springs or top spacers to make up for the emulator.
I had to cut and change the top of my damper rod  to take the emulator. but $900 seems alot

Was that just for the emulators? Most of their late 70's yz125 kits are listed for under 200

I have emulators on all my vintage bikes, big improvement. Proper spring rate for your weight and riding style is equally important. Very easy to tune, but you have to willing to play with them.  If you  look around, they can be bought for around 130-140.

I had a set of YSS in my Yz 125 G and it made a huge differance especially on sharp edge bumps  took the sudden shock out of them so you hit them faster without the bike moving. A+ idea highly reccomended

To fit eliminators correctly you also have to change the springs.  Heavier or lighter main springs.  There is also a company in the UK that makes and fits cartridges to forks.  So they can turn old vintage forks into modern cartridge forks.  The catch is you have to give them your forks to do it, because they machine and hone the inside of the forks so the cartridge seals.

Also the dampening of the eliminators is adjustable.

You don't have to go that far

I leaning towards the Race Tech emulators but will wait until I ridden the completed bike before taking the plunge. After looking at the Race Tech website I states that I need adaptors that sit between the damping rod and emulator. This appears to add about 40 mm+/- on top of the damping rod (combined height of emulator and adaptor). Those that have fitted them did you have to alter the length of the fork springs? I also looked at the Race Tech springs and unless Im reading the info wrong it states that they are 375mm long where the originals are 575mm. At any rate I have the part numbers for the emulators and adaptors so will buy locally and they can then supply springs so if I get wrong ones they are easily returned!!

Be careful with easily returned. If you order them ( not in stock, most likely with vintage stuff ) you will not be able to return them. Check suppliers terms first.

I'll be sure to check there returns policy beforehand!!
